Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of speed-limiting control device of home elevator is provided, to guarantee the operating safety of elevator, improve the product design of elevator.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of speed-limiting control device of home elevator, comprise two beam bodies staggered relatively, two beam bodies connect by connecting rod, one group of speed-limiting control device is installed all respectively on each beam body, described speed-limiting control device comprises the fag end drag-line, be connected electrically in the safety switch on the elevator control circuit, the handle assembly, handle assembly elastic limit device and the switch that be used for to disconnect safety switch re-pack, described fag end drag-line is fixedly mounted in the end of connecting rod, described handle assembly one end is captiveed joint with connecting rod, the other end is then captiveed joint with the voussoir of safety tongs by a safety tongs lifting rod, and the two ends of described handle assembly elastic limit device are connected with the handle assembly with the beam body respectively.
Described handle assembly elastic limit device comprises extension spring seat and extension spring, and the two ends of described extension spring are connected with extension spring seat and handle assembly respectively, and extension spring is compressive state, and the elastic force of while extension spring is that 250N is to 300N.
Described safety tongs lifting rod is double-screw bolt, and described handle assembly is located by connecting by mandrel and double-screw bolt.
According to above technical scheme, can realize following beneficial effect:
The present invention is by installing the handle assembly regularly on connecting rod, and an end of handle assembly is installed switch and is re-packed, the other end then is connected with the voussoir of safety tongs by the safety tongs lifting rod, when then elevator speed surpassed restriction speed, velocity limiter shut down, and the governor rope that is connected with the fag end drag-line can lift connecting rod of the present invention, thereby drive the handle assembly rotation that is connected on the connecting rod, by the safety tongs lifting rod voussoir of safety tongs is mentioned synchronously, clamp guide rail, car is by stop; Meanwhile, handle the rotatablely moving of assembly will drive the switch rotation that re-packs, and makes safety switch disconnect, and namely the control circuit of elevator disconnects, and forces the drg dead electricity to be braked.Hence one can see that, and the present invention is simple in structure, and the velocity limiter of itself and home lift is united use, when cage operation speed surpasses restriction speed, and safety switch action message when can realize the safety tongs action by pulling effectively.Be that the present invention can be when the elevator interruption of service takes place, in time and precision maneuver, the stop car disconnects short circuit, thereby improves company's competitiveness of product.
Description of drawings
Fig. 1 is structural representation of the present invention;
Wherein: 1 is right upright beam body; 2 is connecting rod; 3 is safety switch; 4 is the upright beam body in a left side; 5 is mandrel; 6 is the fag end drag-line; 7 is double-screw bolt; 8 is safety tongs; 9 are the extension spring seat; 10 are extension spring; 11 are the handle assembly; 12 re-pack for switch.
The specific embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment involved in the present invention without limitation, explains technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figure 1, speed-limiting control device of home elevator of the present invention, comprise two beam bodies staggered relatively, be the upright beam body 4 in a left side staggered relatively, the left and right sides and right upright beam body 1 shown in the figure, two beam bodies connect by connecting rod 2, one group of speed-limiting control device is installed all respectively on each beam body, described speed-limiting control device comprises fag end drag-line 6, be connected electrically in the safety switch 3 on the elevator control circuit, handle assembly 11, handle assembly elastic limit device and the switch that be used for to disconnect safety switch 3 re-pack 12, described fag end drag-line 6 is fixedly mounted in the end of connecting rod 2, described handle assembly 11 1 ends are captiveed joint with connecting rod 2, the other end is then captiveed joint with the voussoir of safety tongs 8 by a safety tongs lifting rod, and the two ends of described handle assembly elastic limit device are connected with handle assembly 11 with the beam body respectively.Described handle assembly elastic limit device comprises extension spring seat 9 and extension spring 10, and the two ends of described extension spring 10 are connected with extension spring seat 9 and handle assembly 11 respectively, and extension spring 10 is compressive state, and the elastic force of while extension spring 10 is that 250N is to 300N.Described safety tongs lifting rod is double-screw bolt 7, and described handle assembly 11 is located by connecting by mandrel 5 and double-screw bolt 7.
The present invention arranges corresponding predetermincd tension by regulating extension spring 10, can prevent that elevator governor rope in service from causing the misoperation of safety tongs lifting rod, causes safety tongs 8 voussoirs to the mistake braking of cage operation; When the safety tongs lifting rod drives safety tongs 8 actions, rotation that can drivening rod 2, touch switch 12 rotations that re-pack make safety switch 3 disconnect, namely the control circuit of elevator disconnects, and forces the braking of drg dead electricity.This is simple in structure, has not only realized the teamwork of velocity limiter and safety tongs 8, and cuts off the safety return circuit switch simultaneously, makes that the safety performance of whole elevator is more reliable.
During installation, the velocity limiter of the present invention and home lift is united installation, namely use governor rope to pass through fag end drag-line 6 and be connected with velocity limiter.In addition, by handle assembly 11, connect safety tongs 8 and safety switch 3, when elevator overspeed, handle assembly 11 can move rapidly, makes the switch that is connected with handle assembly 11 re-pack 12 when touching safety switch 3 and make that elevator control circuit cuts off the power supply, and can also impel the safety tongs lifting rod that is connected with the assembly 11 of shaking hands to mention the voussoir of safety tongs 8, to clamp guide rail, impel car by stop.In addition, after assembling is finished, adopt spring balance to lift part safety tongs lifting rod vertically upward, the power of lifting should reach this with slip-knot bolt and regulating part extension spring 10 and lift power at 250N between the 300N.
